 ## Usage
-See 'self_library.m' to reproduce the results for unmanned surface vehicles. See 'SINDY_npsAUV_optim.m' to reproduce the results for unmanned underwater vehicles.
+Take the underwater vehicle as an example. Run the `GetModel.m` file to get the hyperparameters $\lambda$. Run the file several times to obtain stable values. Run the `SINDY_npsAUV_optim.m` file to get the simulation results for the NPS-AUV.
 
 ## Workflow of the proposed identification method
 The framework of the proposed approach is as follows.
